Subaru Oil Change Kit vs Pennzoil Ultra Platinum 0W-40 Motor Oil

The Subaru kit is the right pick for a turbo EJ owner who wants the factory fill and a guaranteed-correct filter and crush washer in one box. The Pennzoil bundle is a different product: 0W-40 oil in quart bottles plus a filter, aimed at high-output engines like the SRT Viper and Demon, not at a stock WRX. On build and fit, the Subaru kit wins for these cars; Pennzoil wins on oil quality and its 4.8 rating from 873 owners, but only if 0W-40 is the grade your engine calls for.

• Choose the Subaru kit if you drive a 2002-2021 WRX, STI, Forester XT or Legacy GT and want the exact 5W-30 fill, filter and drain washer in one order.
• Choose the Pennzoil bundle if your engine specifies 0W-40 and you want a top-tier full synthetic with a filter included.
